Automation and Monitoring System for Temperature and Humidity of Drying Parameters in a Cabinet using Arduino

Abstract

An automation temperature and monitoring system is a setup that uses various sensors and automated processes to continuously monitor and control temperature-related parameters in a given environment. Such systems are commonly used in industrial, commercial, and residential settings to ensure optimal conditions, enhance energy efficiency, and improve safety. This study uses a DHT-22 sensor to develop and construct a temperature-humidity monitoring system for a cabinet drier. Android applications can access this monitoring system, allowing for anytime, anywhere monitoring of the drying parameters. The creation of hardware and software served as the research methodology. The error value is 0.5 and the deviation is 0.0 based on the test and findings of the DHT22 sensor readings compared with conventional measurement devices (PT100 type thermocouple). The average temperature, measured every 30 minutes ten times, is 55.79 °C with a standard deviation of 0.07 °C, according to the findings of the repeatability test. A low error number and a low deviation value both point to excellent precision and accuracy for the sensor, respectively. During the course of 7 hours of drying, the evaluated product's water content—cassava slices—went from 68.92% to 15%. On Android devices, the parameter data from the measurement has been successfully shown through the internet network.
